如何在实时服务器中设置多个站点?

I had been asked a question that, Is it possible to setup multiple site on live server?

I was confused. I had an idea about local server.In local server you can do with making entries in machine host file.

Please anyone guide me about this.

Sure, it works exactly the same as on local server but instead of editing hosts file you have DNS server, which can translate domains to IP adresses. Next, Apache server splits requests into domains by Host header in HTTP request.
